This episode features a strange signal from deep space, which could be a plot straight out of a Hollywood film. But this radio signal was detected by a NASA mission called ARCADE, which flew above the atmosphere suspected from a balloon to capture light from the first stars and galaxies that formed in the Universe. When data showed something totally unexpected, that's when things got interesting. We interviewed Al Kogut and Dale Fixsen about this discovery, ARCADE, and how you can also detect this mysterious radio signal from outer space with any FM radio.

After taking some time off to seek listener feedback and consider the future direction of our podcast, Blueshift is back with a new episode to kick off 2009! For our re-launch, we've focused our first episode on another recently launched NASA project - the Fermi Gamma-ray Space Telescope - and the exciting gamma-ray bursts that it observes.

Welcome to the December 2007 episode of Blueshift, from NASA Goddard Space Flight Center. We're celebrating the new year with a look at the typical life cycle of NASA missions and the typical day of our science staff. We'll start with a look back at the FUSE mission, which ceased operations earlier this year. Then we'll give you an inside look at what it takes to make a mission happen - from the birth of ideas to the day-to-day operation of a satellite after launch.

Welcome to the November 2007 episode of Blueshift, from NASA Goddard Space Flight Center. This month, find out what it's like to spend a summer vacation at NASA in interviews with some of our 2007 interns. Also, join us for a birthday party that's out of this world... happy 10th birthday, ACE! And finally, we'll share the answer to the Episode 4 brain teaser.

Welcome to a special episode of Blueshift! As we approach another year of Nobel Prizes, we are releasing our full-length interview with NASA's own Nobel Laureate, John Mather (an edited version appeared in Episode 4). Learn more about cosmology, Dr. Mather's new position at NASA Headquarters, the importance of small missions, and the exciting future of the James Webb Space Telescope.

Welcome to the July 2007 episode of Blueshift, from NASA Goddard Space Flight Center. Catch up on the latest astronomy headlines, and listen to our audio scrapbook from the American Astronomical Society meeting in Hawaii. For this episode, we interviewed Dr. John Mather, co-winner of the 2006 Nobel Prize in Physics. Dr. Mather talks about cosmology, NASA missions, winning the Nobel Prize, and his induction into a little-known Swedish student organization. We've also got a new brain teaser - and we're eagerly awaiting your answers at our website!

Welcome to the June 2007 episode of Blueshift, from NASA Goddard Space Flight Center. We're featuring X-ray astronomy this episode - listening to black holes and learning about what it takes to build an X-ray telescope. We interviewed Jerry Bonnell, co-curator of the Astronomy Picture of the Day, for a behind-the-scenes look at the website. We'll wrap things up with a new question from the mailbag, and a brain teaser.

Welcome to the May 2007 episode of Blueshift, from NASA Goddard Space Flight Center. We'll discuss our search for Earth-like planets outside of our own Solar System. We'll also look into gamma ray bursts, and how the Swift satellite team is working to solve their mysteries. This episode includes a brain teaser and mailbag question.

Welcome to the first episode of Blueshift, from NASA Goddard Space Flight Center. This episode will tell you a little about what we do here, and features the inventions and innovations of the James Webb Space Telescope (JWST).
